作者:admin 来源:本站 发布时间:2018-09-17 14:35:59 浏览次数:57
21 世纪是信息化的时代,手机、电脑等3C产品的普及,方便人们生活的同时,给我们带来了严重的视觉困扰。近视就是常见的屈光不正,首先近视不可以被治愈大家要知晓,其次近视框架眼镜是目前矫正视力安全稳定的方式之一,而近视眼镜的最重要零件便是眼镜片。下面明月要为给大家简要介绍一下目前市场上矫正视力的近视眼镜的镜片(光学矫正透镜)是由哪些材料构成的。
The 21st century is an era of information. The popularization of 3C products such as mobile phones and computers has brought us serious visual problems while facilitating people's lives. Myopia is a common refractive error, first myopia can not be cured everyone should know, secondly, myopia frame glasses is currently one of the safe and stable way to correct vision, and the most important part of myopia glasses is the lens. The following month to give you a brief introduction to the current market correction of myopia glasses lenses (optical correction lens) is made of what materials.

水晶眼镜镜片
Crystal eyeglass lens
水晶近视眼镜镜片的主要成分是二氧化硅,分为无色和茶色两种。这种近视眼镜镜片的优点是坚硬、不易磨损、不易潮湿(雾气不易在其表面保留),热膨胀系数小(吸热性不好)。但是此类近视眼镜镜片也有一些缺点,如几乎不防紫外线,易引起视觉疲劳,密度不均匀,易含有杂质,有双折现象(看物体有重影)
The main ingredient of crystal glasses is silica, which is divided into two kinds: colorless and tea colored. The advantages of this kind of myopic lens are hard, not easy to wear and tear, not easy to wet (mist is not easy to retain on its surface), small coefficient of thermal expansion (poor heat absorption). But this kind of myopic glasses also have some shortcomings, such as almost no protection against ultraviolet rays, easy to cause visual fatigue, uneven density, easy to contain impurities, double fold phenomenon (see objects have double image)

玻璃眼镜镜片
Glass spectacles lenses
玻璃近视眼镜镜片的主要原料是光学玻璃(SiO2)。其光学性质优越,透光率和机械化学性能都比较好,折射率稳定。但是这种玻璃镜片易碎,材质偏重。
Glass spectacles are mainly made of optical glass (SiO2). Its optical properties are superior, its transmittance and mechanical and chemical properties are relatively good, and its refractive index is stable. But this glass lens is fragile and the material is heavy.

济南玻璃镜片

亚克力镜片的原料是聚甲基丙烯酸甲酯。优点:比玻璃近视眼镜片要轻,不易碎。缺点:表面硬度不及玻璃片;光学性能不及玻璃片。
The raw material of acrylic lens is polymethyl methacrylate. Advantages: lighter than glass spectacles, not fragile. Disadvantages: surface hardness is not as good as glass; optical properties are not as good as glass.
2.CR-39镜片
2.CR-39 lenses
CR-39镜片的原料是丙烯基二甘醇碳酸酯。优点:质量轻;耐冲击、不易碎、安全感强;加工方便,用途广;可染成各种颜色。 缺点:镜片耐磨性较差,易擦伤折,射率低。
The raw material of CR-39 lens is propylene glycol two glycolate carbonate. Advantages: light weight; impact resistance, not easy to break, strong sense of security; easy processing, wide use; can be dyed into a variety of colors. Disadvantages: poor wear resistance, easy abrasion and low firing rate.
3.PC超韧镜片
3.PC super tough lenses
PC超韧镜片的原料是聚碳酸脂。优点:抗冲击能力特别强,号称“宇宙片”,适合运动型人事,在不镀膜的情况下,几乎可以100%防紫外线。缺点:表面硬度低,易划伤,热稳定性较差,加工困难。
The raw material of PC super tough lenses is polycarbonate. Advantages: Strong impact resistance, known as "cosmic film", suitable for sports personnel, without coating, almost 100% UV protection. Disadvantages: low surface hardness, scratch, poor thermal stability and difficult processing.
4.聚氨酯镜片
4. polyurethane lenses
超韧镜片、MR系列镜片的原料是聚氨酯。优点:高阿贝数,视物清晰透彻,视觉质量佳;网状的分子结构,抗冲击性能优异,安全、不易碎。
The raw materials of super tough lenses and MR series lenses are polyurethane. Advantages: High Abbe number, clear and transparent vision, good visual quality; Mesh-like molecular structure, excellent impact resistance, safety, not fragile.
